ASCII art in the optparse description

I'm making a shell script with the optparse module, jut for fun, so I wanted to print a nice ascii drawing in place of the description.

Turns out that this code:

parser = optparse.OptionParser(
    prog='./spill.py',
    description=u'''
  /     \                                     
  vvvvvvv  /|__/|                             
      I   /O,O   |                            
      I /_____   |      /|/|                 
     J|/^ ^ ^ \  |    /00  |    _//|          
      |^ ^ ^ ^ |W|   |/^^\ |   /oo |         
       \m___m__|_|    \m_m_|   \mm_|         
''',
    epilog='''
        Las cucarachas lograron con exito su plan, echando a los pestilentes sangre caliente de sus cajas de cemento. 
Ahora el hombre es una especie errante en el espacio, un vagabundo errante en las estrellas.''')

renders like this:

$ ./bin/spill.py -h
Usage: ./spill.py [options]

   /     \                                        vvvvvvv  /|__/|
I   /O,O   |                                   I /_____   |      /|/|
J|/^ ^ ^ \  |    /00  |    _//|                 |^ ^ ^ ^ |W|   |/^^\ |   /oo |
\m___m__|_|    \m_m_|   \mm_|

Options:
  -h, --help            show this help message and exit
#.... bla bla bla, etc

I've tried a varying combination of slashes, newlines and espaces without success.

Can you, friend pytonista, help me display Totoro properly?
